PRIORITY

This application claims priority under 35 U.S.C. § 119(a) to Korean Application Serial Nos. 10-2015-0133553 and 10-2016-0066487, which were filed in the Korean Intellectual Property Office on Sep. 22, 2015 and May 30, 2016, respectively, the entire content of each of which is hereby incorporated by reference.

BACKGROUND

1. Field of the Disclosure

The present disclosure relates generally to an electronic device, and more particularly, to an attachable/detachable electronic device.

2. Description of the Related Art

While various functions have been incorporated in an electronic device, such as a smart phone or a tablet personal computer (PC), convenience of use may still be somewhat unsatisfactory because such an electronic device has a structure that was designed mostly in consideration of portability. For example, the size or volume to be output may be limited, and inputting various information may be inconvenient. Accordingly, various types of external devices that are interlockable with such an electronic device (e.g., a docking station) have been proposed for expanding of the functionality of the electronic device (e.g., a function of an input/output device).

External devices that are interlockable with an electronic device may provide a charge function when the electronic device is cradled thereon, may be equipped with a separate speaker phone for outputting sound, or may be equipped with a keyboard in for providing an input device function. Accordingly, an external device, which is interlockable with the electronic device, may expand the functionality of the electronic device and/or may improve convenience in using the electronic device.

However, while the convenience and functionality of using an electronic device may be improved by expanding the functions of the electronic device by using an external device (e.g., a docking station) that is interlockable with the electronic device, it may still be inconvenient to carry the external device separately from the electronic device.

SUMMARY

Accordingly, an aspect of the present disclosure is to provide an electronic device that easily couples to an external device, which may be conveniently carried (for example, by being coupled to the electronic device).

Another aspect of the present disclosure is to provide an electronic device that can stably maintain a coupled state between the electronic device and an external device in order to carry the external device.

Another aspect of the present disclosure is to provide an external device that is conveniently carried while being coupled to an electronic device.

In accordance with an aspect of the present disclosure, a portable electronic device is provided, which includes a housing, a magnet positioned within the housing, and an elastic body connected to the magnet. At least a portion of the elastic body changes a shape or a position thereof, in response to a change of a magnetic force of the magnet.

In accordance with another aspect of the present disclosure, a portable electronic device is provided, which includes a housing, a magnet positioned within the housing, and an elastic body connected to the magnet. At least a portion of the elastic body is moveable from a first position corresponding to a first face of the housing to a second position corresponding to a second face of the housing, in response to a change of a magnetic force of the magnet.

In accordance with another aspect of the present disclosure, a portable electronic device is provided, which includes a housing, a magnet positioned within the housing, and an elastic body connected to the magnet. At least a portion of the elastic body is moveable to be spaced apart from one face of the housing, in response to a change of a magnetic force of the magnet.

DETAILED DESCRIPTION

Hereinafter, various embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that there is no intent to limit the present disclosure to the particular forms disclosed herein; rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure.

In describing the drawings, similar reference numerals may be used to designate similar constituent elements.

Herein, terms used to describe specific embodiments are not intended to limit the present disclosure. Singular forms are intended to also include the plural forms, unless the context clearly indicates otherwise.

The terms “include” and “have” indicate the existence of a feature, a number, a step, an operation, a structural element, parts, or a combination thereof, and do not exclude the existences or probability of an addition of one or more other features, numeral, steps, operations, structural elements, parts, or combinations thereof.

Unless defined differently, all of the terms used herein, which include technical terminologies or scientific terminologies, have the same meanings as understood by a person skilled in the art to which the present disclosure belongs. Terms defined in a generally used dictionary are to be interpreted to have the same meanings as the contextual meanings in the relevant field of art, and are not to be interpreted to have ideal or excessively formal meanings unless clearly defined as such in the present specification. In some cases, even a term defined in the present disclosure should not be interpreted to exclude embodiments of the present disclosure.

Herein, the expressions “A or B”, “at least one of A or/and B”, and “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expression “A or B”, “at least one of A and B”, and “at least one of A or B” refer to (1) including at least one A, (2) including at least one B, or (3) including all of at least one A and at least one B.

Expressions such as “a first”, “a second”, “the first”, and “the second” may modify various components regardless of order and/or importance, but do not limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both items are user devices. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present disclosure.

When one element (e.g., a first element) is described as being “(operatively or communicatively) coupled with/to or connected to” another element (e.g., a second element), the first element may be directly connected to the second element or the first element may be indirectly connected to the second element via yet another element (e.g., a third element). However, when the first element is described as being “directly connected,” or “directly coupled” to the second element, there are no intervening elements therebetween.

The term “configured to” may be alternated with, for example, “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of”. The term “configured to” may not necessarily imply “specifically designed to” in hardware.

Alternatively, the expression “device configured to” may indicate that the device, together with other devices or components, “is able to”. For example, the phrase “a processor adapted (or configured) to perform A, B, and C” may indicate a dedicated processor (e.g., embedded processor) only for performing A, B, and C or a generic-purpose processor (e.g., central processing unit (CPU) or application processor (AP)) that can perform A, B, and C by executing one or more software programs, e.g., stored in a memory device.

Herein, an electronic device may be a terminal, a portable terminal, a mobile terminal, a communication terminal, a portable communication terminal, a portable mobile terminal, a display device or the like.

For example, the electronic device may be a smartphone, a portable phone, a game player, a television (TV), a navigation device, a heads-up display unit for a vehicle, a notebook computer, a laptop computer, a tablet PC, a personal media player (PMP), a personal digital assistants (PDA), a mobile medical device, a camera, a wearable device (e.g., smart eyeglasses, an electronic bracelet, an electronic appcessory, an electronic necklace, a smart mirror, or a smart watch), etc. The electronic device may be implemented as a pocket sized portable communication terminal having a wireless communication function.

Further, the electronic device may be a flexible device or a flexible display device.

The electronic device may communicate with an external electronic device, such as a server or the like, and/or perform an operation through an interworking with the external electronic device. For example, the electronic device may transmit an image photographed by a camera and/or position information detected by a sensor unit to the server through a network. The network may be a mobile or cellular communication network, a local area network (LAN), a wireless local area network (WLAN), a wide area network (WAN), an Internet, a small area network (SAN), etc., but is not limited thereto.

FIG. 1 illustrates an electronic device coupled to an external device according to an embodiment of the present disclosure; FIG. 2 illustrates an electronic device separated from an external device according to an embodiment of the present disclosure; FIG. 3 illustrates an electronic device cradled on an external device according to an embodiment of the present disclosure; and FIG. 4 illustrates an electronic device cradled on an external device according to an embodiment of the present disclosure.

Referring to FIGS. 1 to 4, an electronic device 100 includes a housing 101, which includes a front cover 102 and a rear cover 104. The front cover 102 and the rear cover 104 may be integrally formed with each other or may be formed in a separated form. The front cover 102 is mounted on a front face of a bar-type or a plate-type housing 101. Thus, the front face of the housing 101 may be closed due to the front cover 102. The front cover 102 includes a display 132, which may output visual information, such as an image or a text, through a screen area. The front cover 102 may include a touch panel for receiving a user input. Although FIGS. 1-4 illustrate the display 132 on the front cover 102 of the electronic device 100, a display may also or alternatively being included on the rear cover 104 of the electronic device 100.

The electronic device 100 may implement various functions by including various input/output devices and sensors, such as a power button, a volume control button, a speaker module, a microphone module, a camera module, an optical proximity sensor, and a gyro sensor.

A user may perform, through the electronic device 100, storage or input/output of various information or information retrieval by connecting to a network.

The electronic device 100 may be coupled to the external device 200, and have an appearance similar to a laptop computer in a coupled state.

The external device 200 includes a mounting recess 213 formed on a face 211 of the external device 200. The mounting recess 213 is positioned at a side edge of the face 211.

Referring to FIG. 3 and FIG. 4, at least a portion of the electronic device 100 is inserted into, or fastened to, the mounting recess 213, such that the electronic device 100 is cradled on the external device 200 in an inclined state.

Referring to FIG. 1, the electronic device 100 is coupled to the external device 200 on the face 211 of the external device 200, such that the front cover 102 of the electronic device 100 faces the face 211 of the external device 200.

The external device 200 includes a keyboard 215 disposed on the face 211. For example, the input device of the electronic device 100 may be expanded by coupling the electronic device 100 to the external device 200.

The mounting recess 213 is positioned at a side of the keyboard 215.

While various embodiments of the present disclosure herein are described with reference to an example in which the external device 200 is provided with a keyboard 215, the external device 200 may also or alternatively include, for example, a touch pad, a speaker module, a storage medium, and/or a communication module. Accordingly, it is possible to improve the performance of the electronic device 100 or to expand the functionality of the electronic device 100.

As illustrated in FIGS. 3 and 4, when the electronic device 100 is cradled on the external device 200 (e.g., to be inclined), the electronic device 100 and the external device 200 have an appearance similar to that of an unfolded laptop computer. Accordingly, the electronic device 100 may provide various functions, and may be utilized similarly to a laptop computer by being combined with the external device 200.

The electronic device 100 and the external device 200 may include a fixing device for stably maintaining the coupled state. For example, the fixing device may be formed as a mechanical fastening structure, such as a hook and a hook, or a hook and a recess.

The electronic device 100 and the external device 200 may also include a fixing device in which a magnet is used to stably fix the electronic device 100 to the external device 200 without deteriorating the appearance thereof.

FIG. 5 illustrates an enlarged portion of an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 5, the front cover 102 of the housing 101 includes a window 121, the display 123, and a magnet 131. The window 121 is mounted on the front cover 102 of the housing 101, and may be manufactured from a transparent material that allows light to penetrate therethrough. The display 123 is disposed on the inner face of the front cover 102 (e.g., the inner face of the window member 121). The display may output a screen (e.g., contents, an image, a video image, and/or a text).

The magnet 131 is disposed at a side edge of the front cover 102 (on the inner face of the window member 121, at a side of the display 123).

The electronic device 100 also includes an elastic body 135. The magnet 131 is arranged or mounted on the elastic body 135 to form a magnetic module 103.

Further, a magnetic module, which is similar to, or the same as, the magnetic module 103, i.e., a second magnetic module, may be disposed inside the external device 200. The polarities of the magnetic module 103 and the second magnetic module may be different from (opposite to) each other.

For example, the magnetic module 103 (e.g., a magnet having a first polarity (e.g., S-pole)) may be disposed in the electronic device 100, and the second magnetic module (e.g., a magnet having a second polarity (e.g., N-pole)) may be disposed in the external device 200. The magnetic module 103 may have a shape that is the same as, or similar to, the second magnetic module.

FIG. 6 illustrates a magnetic module of an electronic device in a disassembled state according to an embodiment of the present disclosure, and FIG. 7 illustrates the magnetic module of the electronic device in an assembled state according to an embodiment of the present disclosure. For example, a magnetic module 603, as illustrated in FIGS. 6 and 7, may be substituted for the magnetic module 103 in FIG. 5 and/or in the external device 200.

Referring to FIGS. 6 and 7, the magnetic module 603 includes magnets 631 and an elastic body 635. The magnetic module 603 further includes a holder 633, which may be made of a material that is different from that of the elastic body 635.

The magnets 631 are arranged along the elastic body 635. The magnets 631 generate an attractive force (or a repulsive force) with an external object (e.g., an object that is capable of having a magnetic force). For example, the coupled state of the electronic device 100 to the external object can be maintained through an attractive force generated between the magnets 631 and the external object (e.g., the above-mentioned external device 200).

The holder 633 may fix the magnets 631 in a predetermined arrangement to the elastic body 635. The holder 133 includes recesses corresponding to the magnets 631, respectively. The magnets 631 may be mounted on the elastic body 635 while being individually fixed to the holder 633.

Alternatively, the holder 633 may be integrally formed with the magnets 631 and/or the elastic body 635, for example, through an insert injection molding method.

Alternative, the magnets 631 themselves may be directly mounted on, or fixed to, the elastic body 635, without using the holder 633.

The elastic body 635 includes a fixing part 635 a, and elastic parts 635 b that are inclined from opposite ends of the fixing part 635 a. For example, the elastic body 635 may be made through sheet metal working of a metal plate. The central portion of the elastic body 635 may be formed as a fixing part 635 a that is substantially parallel to the front cover 102. The opposite end portions of the elastic body 635 may be formed as elastic parts 635 b that are formed to be inclined with respect to the fixing part 635 a. The fixing part 635 a may provide a space (or a surface) to accommodate or mount the magnets 631 and/or the holder 633 to which the magnets 631 are fixed.

Openings 635 c are formed in the opposite ends of the fixing part 635 a, respectively, e.g., by partially cutting the fixing part 635 a and bending the cut portions. The elastic force provided by the elastic part 635 b may vary depending on the size of the openings 635 c and the bend angle and direction of the cut portions.

Assuming that the surface, on which the magnets 631 are arranged, is a top surface of the elastic body 635, the elastic parts 635 b are formed to be inclined downwardly with respect to the elastic body 635.

FIG. 8 illustrates a magnetic module mounted on an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 8, the magnetic module 603 is fixed to the housing 101 (e.g., the inner face of the front cover 102). Support protrusions 111 a and 111 b are formed on the inner wall of the housing 101. The support protrusions 111 a and 111 b extend in parallel to the inner face of the front cover 102 from the inner wall of the rear cover 104 of the housing 101. For example, when the front cover 102 is coupled to the housing 101, the first support protrusion 111 a and the second protrusion 111 b are disposed on the inner face of the front cover 102 to face each other.

The elastic body 635 is fixed to the inner face of the front cover 102, where the both end portions of the elastic body 635 b are interposed between the inner face of the front cover 102 and the support protrusions 111 a and 111 b. For example, when the elastic body 635 is fixed to the inside of the front cover 102, the elastic part 635 b may provide an elastic force that acts in a direction of causing the fixing part 635 a to be spaced apart from the inner face of the front cover 102. However, when no external force is applied, the magnets 631 remain spaced apart from the inner face of the front cover 102. Accordingly, the elastic body 635 may provide an elastic force that maintains the magnets 631 at a first position corresponding to the rear face of the housing 101 and/or at a second position spaced apart from the front face of the housing 101.

When an external force (e.g., an attractive force) acts on the elastic body 635 and/or the magnets 631 arranged on the elastic body 635, the fixing part 635 a (e.g., the magnets 631) may be in close contact with the inner face of the front cover 102. For example, when a magnetizable external object is positioned on the front cover 102 adjacent to the magnets 631, the fixing part 635 a may come in close contact with the inner face of the window member 121 by the attractive force of the magnets 631 to the external object. For example, as the peripheral magnetic force environment is changed, the elastic body 635 changes in shape or position so as to move the magnets 631 to the second position corresponding to the front face of the housing 101. For example, the magnets 631 may receive the elastic force of the elastic body 635 to remain at a predetermined position, and may be moved between the first position and the second position based on the change of the magnetic force.

The magnetic force, which changes the position of the magnets 631, may be generated by a magnetizable external object or an external device including another magnet (e.g., the external device 200). The housing 101 may be coupled to, and mounted on, the external device 200 by the magnetic force acting between the magnets 631 and the magnets of the external device 200.

It is possible that a magnetic field generated by the magnets 631 may damage some of the user's belongings. For example, the information stored on a magnetic strip of a credit card may be damaged by the magnetic field of the magnets 631. Accordingly, the electronic device 100 may control the magnets 631 to be spaced apart from the inner face of the front cover 102 by using the elastic body 635 in order to suppress the magnetic field generated by the magnets 631 from having an effect on the external environment of the electronic device 100.

As described above, a magnetic module, which is the same as or similar to the above-mentioned magnetic modules 103 and 603, may also be included in the external device 200. For example, the electronic device 100 and the external device 200 may be provided with the magnetic module (e.g., first magnetic module) 103 and a second magnetic module, respectively, and when the electronic device 100 is coupled to face the external device 200, the electronic device 100 may be rigidly coupled or fixed to the external device 200 by the attractive force generated between the first magnetic module 103 and the second magnetic module.

According to an embodiment of the present application, the electronic device 100 or the second magnetic module disposed in the external device 200 do not necessarily have to include the magnets. For example, a flat plate made of a magnetizable material may be installed at a corresponding position of the electronic device 100 or the external device 200 so as to generate an attractive force to the first magnetic module 103.

FIGS. 9 and 10 illustrate an operation of coupling an electronic device to an external device according to an embodiment of the present disclosure. For example, FIGS. 9 and 10 illustrate the electronic device 100 including the magnetic module 603 as illustrated in FIGS. 6 and 7 and the external device 200 including a magnetic module 203 having the same structure as the magnetic module 603.

Referring to FIGS. 9 and 10, the external device 200 (e.g., a speaker device, a display device, a touch pad device, a keyboard device, a docking station, etc.) includes a second magnetic module 203. The second magnetic module 203 includes second magnets 231 and a second elastic body 235. The external device 200 further includes a holder (e.g., a second holder) 233 for mounting the second magnetic module 203 on the second elastic body 235. The second holder 233 may be mounted on the second elastic body 235 such that the second magnets 231 are fixed in a predetermined arrangement. The second elastic body 235 may include a second fixing part and second elastic parts, like the elastic body 635. The second elastic part may be fixed to the inner face of the external device 200 in order to space the second fixing part from the inner face of the external device 200. For example, in when no external force acts, the second fixing part (e.g., the second magnets 231) may be spaced apart from the inner face of the external device 200 by the elastic force provided by the second elastic part 235.

The above-described second magnetic module 203 may be implemented to be similar to, or the same as, the above-described magnetic module 603. For example, in the state where no external force acts, the second elastic body 235 may provide the elastic force so that the second magnets 231 remain spaced apart from the inner face (or inner wall) of the external device 200. For example, each of the magnets 631 and 231 of the magnetic module 603 and the second magnetic module 203 is movable within the electronic device 100 and the external device 200.

Before an external force acts, the magnetic module 603 and the second magnetic module 203 may maintain the magnets 631 apart from the inner face of the front cover 102 and the magnets 231 apart from the inner face of the external device 200, as illustrated in FIG. 9.

The magnets 631 and the second magnets 231 may be arranged to generate an attractive force in relation to each other. For example, when the electronic device 100 is coupled to and facing the external device 200, an attractive force may be generated between the magnets 631 and the second magnets 231. By the attractive force generated between the magnets 631 and the second magnets 231, the magnets 631 (e.g., the fixing part 635 a of the elastic body 635) may come in close contact with the inner face of the front cover 102, and the second magnets 231 (e.g., at least a portion of the second elastic body 235) may come in close contact with the inner face of the external device 200, as illustrated in FIG. 10.

As the magnets 631 and the second magnets 231 come closer contact with the inner faces of the front cover 102 and the external device 200, the spacing between the magnets 631 and the second magnets 231 reduces, and the attractive force generated between the magnets 631 and the second magnets 231 increases. For example, by the attractive force between the magnets 631 and the second magnets 231, the electronic device 100 may be stably coupled and fixed to the external device 200.

When the electronic device 100 is coupled to the external device 200, the coupling remains fixed by the attractive force of the magnets 631 and 231.

By forming a fixing device using magnets, because it is not necessary to form an external mechanical structure for fixing the electronic device (e.g., a hook or a recess), it is possible to make the appearance of the electronic device 100 or the external device 200 more pleasing. Further, because an elastic body including the elastic part is used in installing the magnets, it is also possible to suppress the magnetic force of the magnets from having an influence on the external environment.

FIG. 11 illustrates an electronic device coupled to an external device according to an embodiment of the present disclosure.

Referring to FIG. 11, the second magnets 231 disposed in the external device 200 are directly fixed to the inner face of the external device 200. For example, FIGS. 9 and 10 illustrate a configuration in which the second magnets 231 are installed inside the external device 200 through the second elastic body 235. However, as illustrated in FIG. 11, the second magnets 231 may be fixed to the inner face of the external device 200.

The external device 200 includes a second holder 237 for arranging and fixing the second magnets 231 such that the second magnets 231 can be rigidly fixed to the external device 200.

Because the magnets 631 and/or the second magnets 231 generate an attractive force in relation to each other, it is possible to prevent the electronic device 100 from being released from the external device 200 (e.g., in the upward direction illustrated in FIG. 9). For example, the magnets 631 and/or the second magnets 231 may stably fix the electronic device 100 to the external device 200. Further, it is possible to suppress the electronic device 100 from moving in a horizontal direction (e.g., in the left and right directions illustrated in FIG. 9) with respect to the external device 200 by using an arrangement of the magnets 631 and/or the second magnets 231.

FIGS. 12 to 14 illustrate magnetic modules, which are mounted on an electronic device and an external device, respectively, according to various embodiments of the present disclosure.

Referring to FIGS. 12 to 14, the magnets 631 are arranged on the elastic body 635 (e.g., on the above-described fixing part 635 a), and may be divided into a group of magnets in which a first polarity (e.g., S-pole) is disposed to face the inner face of the front cover 102 (hereinafter, referred to as a “first group G1”) and a group of magnets in which a second polarity (e.g., N-pole) is disposed to face the inner face of the front cover 102 (hereinafter, referred to as a “second group G2”).

On the second elastic body 235, the second magnets 231 may form a third group G3 in which a polarity (e.g., N-pole) is disposed to generate an attractive force with the magnets of the first group G1, and a fourth group in which a polarity (e.g., S-pole) is disposed to generate an attractive force with the magnets of the second group G2. When each of the magnetic modules 603 and 203 includes a plurality of magnets, the magnets disposed in each of the elastic bodies 635 and 235 may be disposed to be spaced apart from each other by a predetermined distance.

For example, when the electronic device 100 is coupled to and facing the external device 200, the magnets of the first group G1 may be disposed to face the magnets of the third group G3, respectively, and the magnets of the second group G2 may be disposed to face the magnets of the fourth group G4, respectively. The attractive force generated between the magnets 631 and the second magnets 231 may stably couple and fix the electronic device 100 to the external device 200.

A repulsive force may also act between the magnets of the first group G1 and the fourth group G4 and/or between the magnets of the second group G2 and the third group G3. The above-described arrangement of the magnets 631 and/or the second magnets 231 is able to suppress the electronic device 100 from moving in the horizontal direction with respect to the external device 200. For example, when the electronic device 100 moves in a first horizontal direction H, a repulsive force generated between the magnets of the first and fourth groups G1 and G4 may suppress the movement of the electronic device 100.
